2SA1037AKT146R from ROHM Semicon, in a TO-236-3(SOT-23-3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Emitter | passive | Emitter terminal of the PNP transistor; VEBO max -6V and BVEBO min -6V at IE = -50µA. |
| 2 | Base | passive | Base terminal of the PNP transistor; hFE 120 to 560 at VCE = -6V, IC = -1mA. |
| 3 | Collector | passive | Collector terminal of the PNP transistor; VCEO -50V, IC -150mA continuous (ICP -200mA at Pw = 1ms single pulse). |
